PROCESS OF MAKING PERFUMES ANDl DISINFECTANTS.

SPECIFICATION forming part of Letters Patent No. 738,274, datedSeptember 8, 1903. Application filed February 5, 1903. Serial No.141,980. (No specimens.)

To @ZZ whom t 71u03/ concern:

Be it known that I, JEAN BARBIN, a subject of the King of Belgium,residing at Brussels, in the Kingdom of Belgium, have invented certainnewand useful Improvements in the Manufacture of Odoriferous,Antiseptic, and Disinfecting Substances, of which the following isaspecification.

The object of the present invention is a process allowing theincorporation Linder particularly economic conditions of volatilesubstances possessing odoriferous, disinfecting, or antiseptic qualitieswith solidified alcohol, so as to form asolid,odoriferous,ordisinfecting substance adapted to be easily molded into tablets, sticks,or anyothershapes and in which the alcohol serves as avolatile orcombu'stible vehicle. Perfumes, essences, and disinfecting or antisepticsubstances cannot usually be incorporated with alcohol when solidified.

For carrying out the invention the process is as follow-s: The alcoholis heated for the necessary time with the substance intended to causeits solidiiication in a digester or similar apparatus connected to acooler in which alcoholic vapors are condensed and afterward passed tothe digester to prevent all loss of alcohol. When the solution iscomp1ete,the heating is interrupted, and the perfume or antisepticsubstance to be incorporated with the solidified alcohol isv separatelydissolved in the ether. This mixture is then introduced into thedigester after the alcohol contained therein has been brought to a com'-paratively much lower temperature by cooling. In this operation theether employed volatilizes at the temperature of the alcohol and isentirely recovered in the cooler by means of a specialarrangement ofconduits connecting the digester with this cooler,which arrangement atthis moment prevents the return of the condensed ether into the digestercontaining the mixture of alcohol and volatile substance andl ofsubstance for solidifying the alcohol. p

The annexed drawing shows, partly in elevation and partly in section, asuitable apparatus for carrying out the process.

A receptacle 1 is used containing water for heating the digester 2therein, which is provided with a level-gage 3, outlet-cock 4,filling-aperture closed by a plug 5,and thermometer 6, and closed at itsupper part by a lid or ter 2 and adapted to conduct into it the productsof condensation. The first-mentioned pipe 10, leading from the digester2 to the coil 1l, is provided With a branch or by-pass 16 and contains astop-cock 17 andan outlet-cock 18. The return-pipe 15 is also providedWith a stop-cock 19`andoutlet-cock 20. The alcohol is heated in thedigester 2 with the substance for producing its soliidication-forexample, steal-ate or margarate of soda. During this operation thestop-cocks 17 19 in the pipes are kept open, so that the vaporizedalcohol passes into the coil 1l, is here condensed,and returns to thedigester 2, the outlet-cocks 18 2O being kept closed. When the solutioncontained in the digester is sufficiently heated-*that is to say, whenthe complete solution of the substance added to the alcohol isobtained-the stop-cocks 17 19 are closed and a certain quantity of'ether containing the perfume or antiseptic or other substance to beincorporated with the solidified alcohol is introduced into the digesterthrough the orifice of the plug 5. On contact with the stillmoderately-heated alcohol the ether volatilizes and passes through thepipe 10 and its branch or by-pass 16 into the coolingcoil 11, in whichit is condensed. The condensed vapors collect partly in said pipe 10between the part thereof connected to the coil 11 and its stop-cock 17and partly in the return-pipe 15, between the end 'thereof connectedWith the coil 1l and its stopcock 19. A

When the operation is completed, it is sufficient to open theoutlet-cocks 18 20 to recover the ether, which can afterward be used inthe succeeding operation. The alcohol solution, volatile substance, andthe substance for solidifying the alcohol are then Withdrawn from thedigester through its outlet-cock 11 and poured into suitable molds oftablet, stick, or other convenient shape.

The above-described process can be em- ICO ployed to advantage not onlyfor the manufacture of solidified perfumes, disinfecting, or antisepticsubstances incorporated with the alcohol, but also in a large number ofpharmaceutical operations. By Way of example of substances which may betreated the following are cited: belladona, arnica, cantharides,capsicnm, eucalyptus, henbane, iodin, sublimate, salicylic acid,menthol, and the like.

What I claim isl. The process herein shown and described forincorporating perfumes, essences, disinfecting and antiseptic substancesin solidified alcohol, consisting in heating the alcohol together with asubstance intended to cause its solidification, dissolving separatelythe perfumes, essences, disinfecting and antiseptic substances in etherand then adding the solution of perfumes, essences, disinfecting andantiseptic substances in ether to the heated alcohol, substantially asand for the purpose set forth.

2. The process herein shown and described for incorporating perfumes,essences, disinfecting and antiseptic substances in solidified alcoholconsisting in heating the alcohol together With a substance intended tocause its solidication until said substance is entirely dissolved,condensing the vapors of alcohol generated during said heating operationand returning the said condensed alcohol-vapors to the heated alcohol,then dissolving separately the perfumes, essences, disinfecting andantiseptic substances in ether then adding the solution of perfumes,essences, disinfecting and antiseptic substances in ether to the heatedalcohol substance and finally condensing and recovering the vapors ofether generated through the contact of the ether mixture with the heatedto the heated alcohol, then dissolving separately the perfumes,essences, disinfecting and antiseptic substances in ether, then loweringthe temperature of the heated alcohol, then adding the solution ofperfumes, essences,disinfecting and antiseptic substances in ether tothe still moderately-heated alcohol and finally condensing andrecovering the vapors of ether generated through the contact of theether mixture with the heated alcohol substantially as and for thepurpose set forth. v

4. The process herein shown and described for incorporating perfumes,essences, disinfecting and antiseptic substances in soliditied alcohol,consisting in adding to a suitably-heated mixture of alcohol and of asubstance adapted to cause its solidilication, the perfumes, essences,disinfecting and antiseptic substances previously dissolved in ethersubstantially as and for the purpose set forth.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.

JEAN BARDIN.
